CCSF Parallax Experiment 1. Two images were taken in front of the Science Building. There are two identical reference positions marked in both photos for alignment. a. Select two objects with a noticeable parallax from the photos. L One of them can be the Francis of Assis statue b. Measure parallactic shifts in degrees, you will need to i. calculate a scale factor, and then compare the two photos, estimating the number of degrees each object shifted ii. iii. refer to the Application of Parallax page in the Parallax Module for the details c. Calculate their distances from the baseline 2. Formula to use for these calculations is as follow: D(m) 57.3x- Baseline AB (m) Parallactic Shift (degrees) 3. Technical Information About the Photos Item Baseline AB Field of View of the Photo Image Dimension Plate-scale Francis ASSIS Statue Right light pole 4. Data Table and Results The definition of the terms in the table refer to the Application of Parallax page in the Parallax Module. Object Name Angle A (degrees) Detail 7.94 15.82 6 meter 87.44° 5,504 x 3,096 57.19" per pixel Angle B (degrees) 5.24 7.94 Parallactic Shift (degrees) 13.18 23.76 Distance from Baseline AB (m)
